YPower is a UK battery brand owned by Yuasa (one of the world's largest battery manufacturers). Their leisure batteries are sold through Halfords, Euro Car Parts, and online retailers. They are positioned as a mid-range option — better than the cheapest no-name batteries but less expensive than the premium brands like Bosch, Varta, and Odyssey.
This guide covers the YPower leisure battery range, how they compare to other UK-available brands, and how to choose the right battery for your van build.
YPower Leisure Battery Range
YPower divides its leisure batteries into three lines.
YPower Standard (Calcium/Calcium)
The entry-level line. These are flooded lead-acid batteries with calcium alloy plates (calcium added to the lead to reduce water loss and corrosion).
Models: YLP40 (40Ah), YLP75 (75Ah), YLP100 (100Ah), YLP120 (120Ah)
Price: £45 (40Ah) to £95 (120Ah)
Pros: Cheap. Widely available (Halfords, Euro Car Parts, Amazon UK). Suitable for basic van builds with low power consumption (LED lights, phone charging, a 12V fridge running 6-8 hours per day).
Cons: Flooded lead-acid — they need venting (hydrogen gas during charging) and occasional water top-up (every 3-6 months). They do not tolerate deep discharge well — discharging below 50% significantly reduces cycle life. A typical YPower calcium battery lasts 2-3 years in a van build before needing replacement.
Best for: Weekend vans, summer-only use, builds with low electrical demands (under 50Ah per day). Not suitable for winter van life.
YPower AGM (Absorbent Glass Mat)
YPower's AGM range uses glass mat separators to hold the electrolyte. These are sealed (no venting required), maintenance-free, and handle vibration better than flooded batteries.
Models: YLP40-AGM (40Ah), YLP75-AGM (75Ah), YLP100-AGM (100Ah), YLP120-AGM (120Ah)
Price: £70 (40Ah) to £140 (120Ah)
Pros: Sealed — mount in any orientation (except upside down). No water top-up. No venting required (some hydrogen venting still occurs but minimal). Better deep-cycle performance than the calcium range — can be discharged to 50% regularly with 300-400 cycles. AGM technology is standard for most campervan leisure battery applications.
Cons: Heavier than calcium equivalents (AGM batteries have more lead in the plates). More expensive. Still limited to 50% depth of discharge (usable capacity of a 100Ah AGM battery is effectively 50Ah). The AGM construction makes them tolerant of vibration but not immune — mounting with a foam base pad is still recommended.
Best for: The standard choice for a medium-budget campervan build. A pair of YPower 100Ah AGM batteries in parallel (200Ah total, 100Ah usable) covers most needs for a full-time van lifer with moderate power consumption.
YPower LiFePO4 (Lithium Iron Phosphate)
YPower entered the lithium market in 2024 with their LP series LiFePO4 batteries. These are drop-in replacements for AGM batteries with the same footprint and terminal positions.
Models: YLP100-Li (100Ah), YLP200-Li (200Ah), YLP300-Li (300Ah)
Price: £300 (100Ah), £550 (200Ah), £800 (300Ah)
Specifications:
- Weight: 11kg (100Ah), 22kg (200Ah)
- BMS continuous: 100A (100Ah), 150A (200Ah), 200A (300Ah)
- Cycles: 4,000 at 80% depth of discharge
- Low-temperature cutoff: No (internal BMS does not disconnect charging below 0°C — install in a heated space)
- Warranty: 3 years
- UK support: YPower UK (based in Ebbw Vale, Wales)
Pros: Lighter than AGM (11kg vs 24kg for a 100Ah equivalent). 4,000 cycles at 80% DoD versus 300-400 cycles at 50% DoD for AGM. Full usable capacity (100Ah usable from a 100Ah battery, versus 50Ah from an AGM). YPower is a UK brand with UK support — returns go to Ebbw Vale, not China.
Cons: More expensive than AGM (3× the cost per Ah). No low-temperature cutoff — if mounted in an unheated garage compartment, the battery can be damaged by charging below 0°C. The 3-year warranty is shorter than Fogstar (5 years) and Renogy (3 years is standard). The BMS is less sophisticated than Fogstar's — it is a basic BMS with overcurrent, over-voltage, and short-circuit protection but no Bluetooth monitoring.
Best for: UK van lifers who want lithium performance on a tighter budget. The £300 100Ah battery is £80 cheaper than a Fogstar 105Ah — the trade-off is no Bluetooth monitoring and a basic BMS.
YPower vs Competitors
YPower 100Ah AGM (£120) vs Numax 100Ah AGM (£115) vs Bosch L5 100Ah (£150)
| Feature | YPower AGM 100Ah | Numax AGM 100Ah | Bosch L5 100Ah |
|---|---|---|---|
| Price | £120 | £115 | £150 |
| Weight | 24kg | 23kg | 22kg |
| Cycles to 50% DoD | 350 | 300 | 400 |
| Warranty | 2 years | 2 years | 3 years |
| UK manufacturer | No (Yuasa/Japan) | No (Taiwan) | No (Germany) |
| Halfords stockist | Yes | No | No |
The YPower AGM offers better cycle life than Numax and is cheaper than Bosch. For most van builds, the YPower AGM is the best value at this price point. Bosch offers better cycle life and a longer warranty but costs 25% more.
YPower 100Ah LiFePO4 (£300) vs Fogstar 105Ah LiFePO4 (£380) vs Renogy 100Ah LiFePO4 (£380)
| Feature | YPower Li 100Ah | Fogstar 105Ah | Renogy 100Ah |
|---|---|---|---|
| Price | £300 | £380 | £380 |
| Weight | 11kg | 10.5kg | 10.8kg |
| Cycles at 80% DoD | 4,000 | 4,000 | 4,000 |
| BMS continuous | 100A | 100A | 100A |
| Bluetooth monitoring | No | Yes | Yes |
| Low-temp cutoff | No | Yes (internal) | Yes (external) |
| Warranty | 3 years | 5 years | 3 years |
| UK location | Ebbw Vale | UK warehouse | UK warehouse |
The YPower LiFePO4 is cheaper than both Fogstar and Renogy but lacks Bluetooth monitoring and low-temperature charging cutoff. For £80 more, the Fogstar gives you Bluetooth monitoring (check voltage/current/temperature on your phone) and a 5-year warranty. For most full-time van lifers, the Fogstar is worth the premium. The YPower lithium makes sense for budget-conscious builds where the savings matter and you can mount the battery in a heated space.
How to Choose
If your daily power consumption is under 40Ah: A single YPower 100Ah AGM (£120) is sufficient. 50Ah usable capacity covers LED lighting (2Ah), 12V fridge (15-20Ah), phone/laptop charging (5Ah), and water pump (1Ah). You will need to recharge every 1-2 days (solar, alternator, or EHU).
If your daily power consumption is 40-80Ah: Two YPower 100Ah AGM batteries in parallel (£240). 100Ah usable capacity. This covers a fridge running 24/7, lights, laptop, fan, and water pump for 1-2 days without charging. The standard setup for a medium-spec van build.
If your daily power consumption is over 80Ah or you want lithium: A single YPower 100Ah LiFePO4 (£300) or Fogstar 105Ah (£380). 100Ah usable (full capacity). Covers everything above plus an inverter (600W) for a coffee machine (15Ah per use) or induction hob (30Ah per use). The lithium battery weighs half as much as the AGM equivalent.
Practical Considerations
AGM vs Lithium decision: If your build budget is under £2,000 for the full electrical system (battery, solar, charger, wiring), use AGM. The £200 saved on the battery buys better solar panels or a more efficient fridge. If your budget is over £2,000, go lithium — the weight saving and usable capacity difference transform how much power you can use.
Mounting YPower batteries: YPower AGM batteries can be mounted on their side (some models) — check the label. Lithium batteries must be mounted upright. Both types need to be secured against movement (use a battery tray and strap) and mounted in a ventilated space (AGM) or a heated space (lithium).
Charging YPower lithium: YPower LiFePO4 batteries need a charge profile of 14.2-14.6V absorption voltage and 13.5-13.6V float voltage. Ensure your solar charge controller, DC-DC charger, and mains charger are programmable for these values. Most Victron, Renogy, and Votronic chargers support this. If you have an older charger with fixed lead-acid profile (14.4V absorption, 13.8V float), set it to the "AGM" setting — the YPower BMS handles slight overvoltage, but the battery will not charge to full capacity.
Where to Buy
- Halfords (YPower AGM range only, £5-£10 premium over online)
- Euro Car Parts (YPower AGM and calcium range)
- Amazon UK (full YPower range including lithium)
- Tayna Batteries (specialist battery retailer, competitive prices, fast delivery)
- Alpha Batteries (online specialist, good for bulk buys)
The Bottom Line
YPower is a solid mid-range battery brand for UK campervan builds. Their AGM range offers the best value at the £100-£150 price point — reasonable cycle life, UK availability, and reliable construction. The lithium range is cheaper than the market leaders but the lack of Bluetooth monitoring and low-temperature protection makes it a compromise.
For most van builds: buy a YPower 100Ah AGM (£120) if you are on a budget, or a pair of YPower 100Ah AGM batteries (£240) for moderate power needs. For lithium, spend the extra £80 on a Fogstar 105Ah — the Bluetooth monitoring and low-temp cutoff are worth the difference for full-time van life.
